Abstract: In this work we study a model food web with three species, originally proposed by Hastings and Powell, that exhibits chaotic dynamics. We propose a spatial version of this model where the predators seek their preys only in a finite neighborhood of their home location. We show that the introduction of finite range interactions leads to the spontaneous formation of patterns (clusters) in the spatial distribution of the species. Besides, the dynamics of the average value of each population changes qualitatively with respect to the chaotic attractor present in the original model. The fundamental parameters of the spatial model are the ranges of interaction of the two higher trophic species. We show that the number and size of the clusters depende on size of these interaction radii. The ratio between them also determines if the average population dynamis will be chaotic or will tend to an stable fixed point
